In this video segment from Cyberchase, there is a valuable Encryptor chip being auctioned off that the CyberSquad needs to purchase in order to save Motherboard. It looks like it will take at least 100 Snelfus to win the bidding. The CyberSquad plans to raise Snelfus by working each day to earn and save Snelfus over a period of 11 days.

Here are some Frame, Focus and Follow-up suggestions for using this video in a math lesson.

What is Frame, Focus and Follow-up?

Frame: If you had to earn $50 to pay for an overnight class trip, and you only had 10 days to earn it, how much would you need to earn each day? Would it be better to try to earn it all in one day, or to spread the work out over a number of days? Why?

Focus: Watch to learn how the CyberSquad plans to earn the Snelfus they need to win the auction for the chip. How do they figure out how much they must earn each day in order to reach their goal? What kinds of math operations do they use?
